HEEL-PRESS.

Specification of Letters Patent.

Patented Oct. 26, 1915.

To all whom it may concern: I

. Beit known that 1, CHARLES O. RYBERG, a citizen of the United States, anda resident of Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Heel-Presses, of which the follow ing is a specification.

This invention relates to presses used in shoe factories for holding a number of heels or heel bodies, the lifts of which are coated with paste or cement, under pressure while the paste is setting, and it has for its chief object to provide a press having two oppositely facing. storage spaces in one of which heels may remain under pressure While heels are being assembled in'the other space .pre-

paratory to receiving pressure.

The invention consists in the improvements which I will now proceed to describe and claim.

1 represents a side elevation of a heel press embodying my invention. Fig. 2 represents an end elevation of the same, parts being shown in section. Fig. 3 represents a sec tion on line 33 of Fig. 2. Fig. 4 represents a section on line H of Fig. 3. Fig. 5 represents a section on line 55 of Fig. 2.

The same reference characters indicate the same parts in all the figures.

My improved press comprises a frame, the lower portion of which is composed of two horizontal bed members 12'located side by side and rigidly connected, said members being preferably formed as a single piece or part. The upper portion oftheframe is composed of two top members 13 located side by side and also preferably formedas. a single piece or part, the bed members and top members being horizontally arranged and rigidly connected by upright rods 14.

15 represents a partition which subdivides the frame into two storage spaces facing in opposite directions. Said partition is relatively thin and may be made of wood or metal, the upper and lower edges of the partition being preferably inserted in slots 16 in the connected parts which form the bed members 12 and too members 18. Each of the storage spaces is adapted to receive a plurality of horizontal rows of heels 17, the lower row of heels being placed upon a bed member 12 with the breasts in contact with the partition 15 as shown by Fig. 5. After each horizontal row is formed it may be covered by a thin spacing strip 18 on which another row of heels is placed, and so on, the operation being repeated until a stack containing the desired number of heelsis formed. The partition 15. not only facilitates proper stacking of the heels or heel bodies, since either surface forms the compartment back against which the articlesjcan be deposited by the operator as he finishes theicoating of them with the adhesive, but it also steadies the stack during compression thereof, so as to reduce liabilityof their bulging out.

In 'each storage space is located a movablepress platen, 19, two platens being employed, one at each side of the partition 15. Each platen is provided. with a screw threadedshank 20 which engages a nut 21 is which isjournaled ina bearing 22 in the Of the accompanying drawings :-F1gure correspondingtop member 13, there being two nuts 21. Each nut is provided at its lower end with a bevel gear 23 which meshes with a bevel gear 2% on a shaft 25 journaled in bearings 26 attached to the top member 18, there being two shafts 25, one for each nut21. Each shaft 25 may be rotated by means of a crank 28 having a socket adapted to be removably engaged with the squared outer end portion 29 of the shaft so that the same crank can be used to rotate each of the shafts. When a stack of heels has been formed in one of the storage spaces of the press, the platen 19in that space is forced downwardly by the described means and caused to exert pressure on the stack. The contents of the storage space last mentioned may be allowed to remain under pressure while the opposite storage space is being charged with heels in the manner above described, after which the last formed stack of heels is put under pressure and the previously or part forming the bed members 12 is provided with a vertical stud or journal 30 which is journaled in a bearing 31 formed in a suitable base 32, the base being pref erably provided with an annular supporting rib 33 with which a similar annular rib '34 on the part forming the base members 12 is in sliding contact. WVhen the frame is mounted to rotate as last described, the shafts 25 extend in opposite directions as shown by Fig. 4 so that a one half rotation of the frame-will bring each shaft into the position formally occupied by the other.

Vertical abutment rods 35 are secured to the central portions of the base and top members in position to extendacross a stack of heels. Each rod is spaced outwardly from the stack as shown by Figs. 2 and 5, so that a wedge 36 may be interposed between its inner side and a vertical strip 37 bearing against the .outer edges of the spacing strips 18. The abutment rods 35 there fore serve to prevent the stack of heels from tipping outwardly from the partition 15. If desired, each abutment rod 35 may be secured at its upper end to a block 38 which is mounted to swing on horizontal pivots 39 so that the abutment rod may be swung outwardly as indicated by dotted lines in Fig. 2.

In practice the described'press is located adjacent to a benchon which an operator assembles the heel liftsand coats them with paste, the operator being enabled first to charge one side or storage space of the press and to put the charge under pressure, and then, without change of position, swing the press and bring the opposite storage space into convenient relation to the bench so that the last mentioned space may be charged while the heels in the other space are held under pressure and while the paste is setting.

I claim 1. A press comprising a frame composed of two horizontal bed members, two horizontal top members located above the bed members, upright standards connecting said bed and top members, and a vertical partition subdividing the frame into two oppositely facing storage spaces, the bottoms of which are formed by the bed members, the opposite faces of said partition forming guides to aline edge portions of the articles stacked in said spaces, press platens movable in said spaces and devices carried by said platens and top members for operating the platens.

2. A press comprising a frame composed of two horizontal bed members, two horizontal top members located above the bed members, upright standards connecting said bed and top members, and a vertical partition subdividing the frame into two oppositely facing storage spaces, the bottoms of which are formed by the bed members, the opposite faces of said partition forming guides to aline edge portions of the articles stacked in said spaces, nuts journaled in the top members and located at opposite sides of said partition, means carried by the top members for rotating said nuts, and press platens movable in said spaces and provided with threaded stems engaging said nuts.

3. A press comprising a frame composed of two horizontal bed members, two horizontal' top members located above the bed members, upright standards connecting said bed and top members, and a vertical partition subdividing the frame into two oppositely facing storage spaces, the bottoms of which are formed by the bed members, the opposite faces of said partition forming guides to aline edge portions of the articles stacked in said spaces, nuts journaled in the top members and located at opposite sides of said partition, said nuts being provided with gears, and shafts j ournaled in the top members and having gears meshing with the gears on the nuts.

4:. A press comprising a frame composed of two horizontal bed members, two horizontal top members located above the bed members, upright standards connecting said bed and top members, and a vertical partition subdividing the frame into two oppositely facing storage spaces, the bottoms of which are formed by the bed members, the opposite faces of said partition forming guides to aline edge portions of the articles stacked in said spaces, press platens movable in said spaces, devices carried by said platens and top members for operating the platens, and upright abutment rods secured to and extending between the central portions of the said bed and top members, and located at the outer sides of said spaces, each rod being adapted to cooperate with removable devices for securing a stack of heels in the corresponding storage space.

5. A press having a single continuous vertical partition the opposite faces of which form guiding surfaces against which articles may be stacked with edge portions in alinement, means for holding stacked articles under pressure with rear edge portions against said partition, and movable abutments to bear against front edge portions of articles while under pressure.

In testimony whereof I have afiixed my signature, in presence of two witnesses.
